Cabriolet car

Abstract

The invention relates to a cabriolet car ( 1 ) comprising a roof provided with a flexible cover ( 3 ) at least in the rear part thereof, wherein the cover ( 3 ) being in a closed position can be tensionally supported with respect to a body ( 7 ) with the aid of a tension bow ( 11 ). In order to open the roof ( 2 ), the tension bow ( 11 ) is displaced to the closed position thereof, wherein said bow is arranged on a closed support element (A) of the body ( 7 ), first upward (AS) and, when the support element is open, backward (RS) and subsequently to the open position, wherein said tension bow is arranged under the plan of the closed support element (A) being displaced downwards (AV). Said invention provides for a first displacement center ( 25 ) for displacing the tension bow ( 11 ) upwards and backwards (AS, RS) and a separate second displacement center for displacing said tension bow downward (AV). When the tension bow is displaced downwards rotating around the second displacement center, the displacement thereof around the first displacement center ( 25 ) is inhibited.

1. Convertible vehicle ( 1 ) with a roof ( 2 ) that has a flexible roof covering ( 3 ) at least in the rear area, wherein, in the closed state, the roof covering ( 3 ) can be held under tension relative to the automobile body ( 7 ) by at least one tension bow ( 11 ), and wherein, to open the roof ( 2 ), the tension bow ( 11 ) can first be displaced upward (AS) from a closed position in which the tension bow lies on a closed supporting structure (A) of the automobile body ( 7 ), then rotated back (RS) with the supporting structure open, and then displaced downward (AV) into an open position located below the level of the closed supporting structure (A), wherein for the upward movement (AS) and return movement (RS) of the tension bow ( 11 ), a first center of motion ( 25 ) is provided, and for the downward displacement (AV) of the tension bow, a second center of motion that is separate from the first center of motion is provided, and during the downward displacement (AV) of the tension bow ( 11 ) about the second center of motion, the motion of the tension bow about the first center of motion ( 25 ) is stopped, wherein during the downward displacement (AV) of the tension bow about the second center of motion, the tension bow ( 11 ) rests on a stop ( 26 ) and does not move relative to the stop ( 26 ) during the entire downward displacement (AV). 
   
   
     2. Convertible vehicle ( 1 ) in accordance with  claim 1 , wherein the motion of the tension bow is stopped by purely mechanical means. 
   
   
     3. Convertible vehicle ( 1 ) in accordance with  claim 1 , wherein during the upward movement (AS) and the return movement (RS) of the tension bow ( 11 ), movement about the second center of motion is stopped. 
   
   
     4. Convertible vehicle ( 1 ) in accordance with  claim 1 , wherein the first center of motion ( 25 ) is a pivot axis. 
   
   
     5. Convertible vehicle ( 1 ) in accordance with  claim 1 , wherein in the open position of the roof ( 2 ), the tension bow ( 11 ) rests on at least one support ( 15 ), which are held on lateral arms ( 14 ), which are connected with a roof frame ( 5 ) that holds the roof covering ( 3 ) from below before the roof frame ( 5 ) is installed on the automobile body ( 7 ). 
   
   
     6. Convertible vehicle ( 1 ) in accordance with  claim 1 , wherein the downward displacement (AV) about the second center of motion is produced by a four-bar linkage ( 17 ;  19 ;  21 ;  24 ). 
   
   
     7. Convertible vehicle ( 1 ) in accordance with  claim 6 , wherein the four-bar linkage ( 17 ;  19 ;  21 ;  24 ) comprises two body-mounted joints ( 17 ;  19 ), one of which rotatably supports a lateral post section ( 18 ) that extends forward and upward in the direction of vehicle travel (F) when the roof ( 2 ) is closed, while the other rotatably supports a short coupling link ( 20 ). 
   
   
     8. Convertible vehicle ( 1 ) in accordance with  claim 7 , wherein the coupling link ( 20 ) and the roof post ( 18 ) are connected with each other by a control link ( 22 ) located between and connected to the coupling and the roof part by joints ( 21 ;  24 ). 
   
   
     9. Convertible vehicle ( 1 ) in accordance with  claim 8 , wherein the center of motion ( 25 ) for the upward movement (AS) and the return movement (RS) of the tension bow ( 11 ) is supported on the control link ( 22 ). 
   
   
     10. Convertible vehicle ( 1 ) in accordance with  claim 8 , wherein an arm ( 27 ) that points to the rear is assigned to the control link ( 22 ) and carries a stop ( 26 ) for limiting the movement of the tension bow ( 11 ) about the first center of motion ( 25 ). 
   
   
     11. Convertible vehicle ( 1 ) in accordance with  claim 10 , wherein when the roof ( 2 ) is closed, the tension bow ( 11 ) is spaced some distance from the stop ( 26 ). 
   
   
     12. Convertible vehicle ( 1 ) in accordance with  claim 10 , wherein at least the height of the stop ( 26 ) can be adjusted. 
   
   
     13. Movable vehicle roof ( 2 ) for a convertible vehicle ( 1 ) having a flexible roof covering (3) at least in the rear area, wherein, in the closed state, the roof covering ( 3 ) can be held under tension relative to the automobile body ( 7 ) by at least one tension bow ( 11 ), and wherein, to open the roof ( 2 ), the tension bow ( 11 ) can first be displaced upward (AS) from a closed position in which the tension bow lies on a closed supporting structure (A) of the automobile body ( 7 ), then rotated back (RS) with the supporting structure open, and then displaced downward (AV) into an open position located below the level of the closed supporting structure (A), wherein for the upward movement (AS) and return movement (RS) of the tension bow ( 11 ), a first center of motion ( 25 ) is provided, and for the downward displacement (AV) of the tension bow, a second center of motion that is separate from the first center of motion is provided, and during the downward displacement (AV) of the tension bow ( 11 ) about the second center of motion, the motion of the tension bow about the first center of motion ( 25 ) is stopped, wherein during the downward displacement (AV) of the tension bow about the second center of motion, the tension bow ( 11 ) rests on a stop ( 26 ) and does not move relative to the stop ( 26 ) during the entire downward displacement (AV).
